How to Handle Research Constructs Without Direct Translation Equivalents
What Does It Mean for a Construct to Have No Direct Language Equivalent?
A research construct lacks a direct language equivalent when no readily available target-language term adequately communicates its intended theoretical meaning.
This does not necessarily mean that people who speak the target language cannot experience or understand the phenomenon.
For example, a language may not have a widely recognized single-word equivalent for a particular educational psychology construct, yet speakers may describe its defining experiences through familiar expressions.
The distinction between lacking a convenient term and lacking a comparable concept is essential.
Researchers should not conclude that a construct is absent from a cultural context merely because its original academic label cannot be translated directly.
Why Are Some Research Constructs Difficult to Translate?
Many constructs are theoretical abstractions rather than directly observable objects.
Terms such as autonomy, resilience, engagement, and agency acquire specialized meanings through disciplinary literature and operational definitions.
Everyday words that appear similar may emphasize different psychological processes, behaviors, or social relationships.
For example, self-efficacy refers to beliefs about capability to perform particular actions. A translation emphasizing confidence as general optimism may not preserve that meaning.
Similarly, learner agency may involve intentional action and influence over learning circumstances rather than independence from other people.
The difficulty may arise from linguistic distinctions, theoretical complexity, cultural practices, or a combination of these factors.
What Is the Difference Between Lexical and Conceptual Equivalence?
Lexical equivalence
The availability of words or expressions in two languages that correspond sufficiently in their linguistic meaning.
Conceptual equivalence
The extent to which the intended theoretical attribute has sufficiently comparable meaning and representation across the contexts being studied.
A construct may lack lexical equivalence while retaining conceptual comparability.
Conversely, two languages may contain apparently equivalent words that refer to different social practices or theoretical attributes.
Translation should therefore be evaluated against the construct definition rather than dictionary correspondence alone.
Does an Untranslatable Word Mean the Construct Does Not Exist in the Target Culture?
No. Such a conclusion would generally exceed what linguistic evidence can establish.
The absence of a familiar label may reflect differences in vocabulary, academic traditions, or how experiences are categorized.
For example, respondents may describe monitoring their learning without recognizing a formal term for metacognitive monitoring.
However, researchers should also avoid assuming that every construct developed in one context necessarily has identical meaning elsewhere.
Some constructs may depend on culturally specific assumptions about behavior, identity, or social relationships.
The appropriate response is empirical and conceptual investigation, not automatic claims of either universality or cultural uniqueness.
What Should Researchers Examine Before Selecting a Translation?
The first task is to separate the construct's theoretical definition from its original linguistic label.
Identify the defining attributes, intended dimensions, observable indicators, and boundaries separating the construct from related concepts.
For example, a measure of academic self-efficacy should distinguish perceived capability from motivation, actual achievement, and willingness to attempt a task.
Researchers should then investigate which target-language expressions communicate those distinctions.
This process follows the broader principle of defining the research construct before developing instrument items.

No strategy is universally superior. The choice depends on the construct, target population, and intended interpretation.
Should You Retain the Original English Term?
Retaining an English technical term may be appropriate when the intended respondents already understand it in the required theoretical sense.
For example, postgraduate researchers working in an English-medium academic environment may recognize certain disciplinary terms.
However, familiarity with a word does not necessarily imply familiarity with its technical definition.
For respondents with limited exposure to the terminology, retaining the English expression may introduce construct-irrelevant language difficulty.
Researchers should investigate actual comprehension rather than assume that educational attainment or language proficiency guarantees conceptual understanding.
Can You Use a Descriptive Phrase Instead of a Single Word?
Yes. A descriptive phrase may communicate a construct more accurately than an unnatural single-word translation.
For example, an expression describing the belief that one can successfully perform a particular task may communicate an aspect of self-efficacy more clearly than a broad term for confidence.
However, the phrase must preserve the construct's defining attributes without introducing unrelated ideas.
It should also fit the item's grammatical structure and response options.
A longer expression may increase reading burden or inadvertently provide respondents with additional cues not present in the original instrument.
Candidate wording should therefore be evaluated for both conceptual accuracy and comprehensibility.
Should You Invent a New Term?
Creating a new term may be considered when existing expressions are inadequate, particularly in specialized academic contexts.
However, introducing a neologism does not establish that respondents understand the intended construct.
A newly coined term may appear precise to researchers while remaining unfamiliar or ambiguous to participants.
Where a new term is necessary, its definition and use should be documented, and respondent comprehension should be investigated.
Researchers should also consider whether established terminology already exists in relevant local scholarship or professional practice.
Inventing terminology should not become a substitute for reviewing the literature and consulting language users.
Can You Add an Explanation to the Questionnaire Item?
Potentially, but an explanation changes the information available to respondents.
For example, adding a definition of learner autonomy before an item may clarify the intended concept.
However, the explanation may also direct respondents toward a particular interpretation or make the adapted task different from the original.
Researchers should evaluate whether the explanation is necessary, neutral, and consistent with the construct.
When cross-language comparability matters, the effect of additional explanatory text deserves particular attention.
Can You Replace an Abstract Construct With Observable Behaviors?
Behaviorally specific wording can sometimes improve comprehension.
For example, rather than asking respondents whether they demonstrate metacognitive monitoring, an item might ask whether they check their understanding while studying.
However, one behavior rarely represents the entire construct.
Replacing abstract terminology with a particular behavior may narrow the measurement domain or change the balance of construct dimensions.
Researchers should distinguish clarifying an existing indicator from redesigning the operational definition.
Substantial changes may require broader instrument development and evaluation.
What If the Construct Has Different Cultural Expressions?
Researchers should examine whether different behaviors can represent the same underlying attribute.
For example, learner autonomy may be expressed through independent planning in one educational setting and through self-endorsed decisions made after consultation in another.
These expressions may be conceptually related, but their equivalence should not be assumed.
The research team should identify the construct's defining attributes and investigate whether proposed indicators preserve them.
The principles for adapting research instruments across cultural contexts are relevant when linguistic problems reveal differences in social or educational practices.
Who Should Evaluate Candidate Translations?
The evaluation should involve expertise appropriate to the linguistic and conceptual problems.
Bilingual translators can examine natural language use and semantic correspondence.
Subject specialists can evaluate theoretical distinctions and construct boundaries.
Measurement specialists can examine item structure, response categories, and scoring implications.
Target-population members can reveal whether candidate expressions communicate the intended meaning.
These perspectives are complementary, as discussed in reviewing translated instruments with bilingual experts and intended respondents.
How Can Cognitive Interviewing Help?
Cognitive interviewing can investigate what respondents believe a translated item asks and how they construct their answers.
For example, a researcher might ask participants to explain a candidate expression for self-efficacy in their own words.
If respondents consistently describe motivation rather than perceived capability, the wording may not represent the intended construct.
Researchers can compare alternative expressions and revise the item when necessary.
However, cognitive interviewing does not independently establish statistical measurement equivalence.
The procedures described in cognitive interviewing for questionnaire development can support this evaluation.
Can Back-Translation Resolve the Problem?
Back-translation may reveal conceptual discrepancies, but it cannot create a direct lexical equivalent where none exists.
A natural descriptive phrase may back-translate differently from the original technical term while preserving the intended meaning.
Conversely, an awkward literal expression may back-translate almost perfectly while confusing respondents.
Researchers should therefore avoid selecting terminology solely because its back-translation resembles the original.
The limitations of back-translation as evidence of instrument equivalence are especially important when constructs have no direct language equivalent.
Does Conceptual Equivalence Guarantee Measurement Equivalence?
No. Even when experts and respondents agree that two expressions represent the same construct, the resulting scores may function differently.
For example, translated response categories may produce different item distributions or relationships among items.
Measurement equivalence may require additional empirical evaluation, particularly when scores are compared across language groups.
Depending on the measurement model, researchers may investigate dimensional structure, item functioning, thresholds, intercepts, or other relevant parameters.
Conceptual review and statistical evaluation contribute different evidence to the validity argument.
When Should You Reconsider the Original Instrument?
Researchers should reconsider the instrument when its defining concepts or indicators cannot be represented adequately in the target context without substantial alteration.
For example, a questionnaire may define academic independence through practices unavailable or inappropriate in the intended educational environment.
Repeated wording revisions may not resolve a fundamental mismatch between the instrument's operational definition and the target context.
In such circumstances, another established measure or a context-specific instrument may be preferable.
Researchers should not preserve an unsuitable instrument solely because it is widely cited.
Can a Context-Specific Instrument Still Be Compared With the Original?
Potentially, but comparability must be established rather than inferred.
Two instruments may address the same broad construct while representing different dimensions or behaviors.
For example, measures of academic autonomy may emphasize different activities across educational contexts.
Similar scale names or numerical score ranges do not establish that their scores are interchangeable.
Where cross-context comparison is essential, researchers should consider appropriate linking or measurement equivalence evidence and acknowledge unresolved differences.
What If the Study Does Not Compare Language Groups?
The researcher may focus on whether the translated instrument adequately measures the construct within the intended population.
Cross-language invariance analysis may not be necessary when no cross-language comparison is intended.
However, content relevance, respondent comprehension, scoring, and appropriate reliability or structural evidence remain important.
Translation difficulties should not be dismissed simply because the study uses only one language.
The goal remains a defensible interpretation of scores in that population.
How Should Unresolved Conceptual Differences Be Reported?
Researchers should describe the original construct, the translation difficulty, candidate expressions considered, and the reasons for selecting the final wording.
Report relevant expert judgments and target-population findings.
If the translated expression represents only part of the original construct, acknowledge that limitation explicitly.
Where the adaptation changes scoring or content, identify the resulting instrument version accurately.
The documentation should follow the principles for recording research instrument modifications.
Watch Out
Do not infer that a construct is absent from a population because its academic label has no direct translation. Equally, do not assume that a convenient translated word preserves the original theoretical meaning. The construct, its linguistic expression, and the evidence supporting its measurement must be examined separately.
